[Mono-list] mono-core still required after using mkbundle --static to make executable

We tried adding --config /etc/mono and got a segmentation fault when we tried to run the exe. However I got in contact with Alex via IRC and he suggested removing everything but the libc entry in the config file. This appears to have worked!
Here is what our final mkbundle command looked like:
mkbundle --static --deps --config /workspace/output/configtest --machine-config /etc/mono/4.5/machine.config Integrate.Identity.Gateway.exe (all dlls with full paths, space separated) -o identity.exe
contents of “configtest” config file (we copied /etc/mono/config and removed everything but libc to make this file):
<dllmap dll="libc" target="libc.so.6" os="!windows"/>

You’re missing the dllmaps that remap „libc“ in p/invoke declarations to libc.dylib/libc.so.6/msvcrt.dll, so the program doesn’t find the library.
Pass --config /etc/mono/config to use the default dllmap config that ships with Mono (after verifying the entries make sense for your target).

We finally got mkbundle --static to build a single executable of our microservice, but when we move it to another machine, it fails to run unless we install mono-core (this is all on Cent0S 7 installs).
I've included the error below, but it appears to be MassTransit library specific while the issue gets resolved with installing mono-core (yum install mono-core). This leads us to believe there is some other issue at hand and the error is misleading.
Our mkbundle command:
mkbundle --deps --machine-config /etc/mono/4.5/machine.config --static Integrate.Identity.Gateway.exe /workspace/output/Integrate.dll /workspace/output/Integrate.Nancy.dll /workspace/output/Nancy.dll /workspace/output/MongoDB.Driver.dll /workspace/output/MongoDB.Bson.dll /workspace/output/Newtonsoft.Json.dll /workspace/output/Newtonsoft.Json.7.0.1.dll /workspace/output/Integrate.Identity.dll /workspace/output/Nancy.Hosting.Self.dll /workspace/output/Integrate.Identity.Storage.dll /workspace/output/Integrate.Identity.Service.dll /workspace/output/MassTransit.dll /workspace/output/Magnum.dll /workspace/output/Integrate.MassTransit.dll /workspace/output/MassTransit.Transports.RabbitMq.dll /workspace/output/Integrate.Cache.Redis.dll /workspace/output/ServiceStack.Interfaces.dll /workspace/output/ServiceStack.Redis.dll /workspace/output/ServiceStack.Text.dll /workspace/output/ServiceStack.Common.dll /workspace/output/nunit.framework.dll /workspace/output/Simple.Mocking.dll /workspace/output/Integrate.Identity.Tests.dll /workspace/output/log4net.dll -o integrateapp.exe
Error when trying to run executable without mono-core installed:

(error text continues but cutting it off here)
Does anyone have any pointers on what we can try next? We've spent a few days on this at this point and are at a dead end.
We use bindingredirect in our app.config if that matters.
